KEY FOR WATCI-IMENS CLOCKS.

Application filed March 30, 1917.

To all whom it may] concern:

Be it known that I, Crmnnns MAURICE PEABODY, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Keys for l/Vatchmens Clocks, of which the following is a specification.

This invention relates to a key for a watchinans clock and securing devices therefor, and the. objects of the invention are to improve upon the means for se-% curing the key to the end of the chain in a simple and inexpensive manner so that the chain will not become twisted and hence easily broken and severed from the key, either by use or design, without showing visible evidence of the fact.

I will now proceed to describe my inven tion with reference to the accompanying drawings and will then point out the novel features in claims: In said drawings:

Figure 1 is a side elevation of a watchmans key shown partly in cross-section, made in accordance with the invention.

Fig. 2 is a view similar to Fig. 1 showing the chain turned ninety degrees.

Fig. 3 is a top view of the upper end of the key.

Fig. 4 is a slightly enlarged perspective view of the locking sleeve.

Referring to the drawings, 1 designates a key for a watchmans clock which in accordance with the present invention is provided with a longitudinal recess 2 situated in the upper end or handle of the key. The reoess 2 is bored and then reamed to provide a continuous overhanging integral flange 3 adjacent the upper end of the key.

The flanged recess just described is adapted to have inserted therein a locking sleeve 4 through the center of which loosely passes a suitable chain or wire rope 5 having secured at its lower end a short cross bar 6 which prevents the end of the chain or rope being pulled through the sleeve although the same is left free to turn in any direction.

The upper end of the sleeve 4 is made slightly greater in diameter across its outer circumference than the inner diameter of the overhanging flange 3, whereas the lower end of the sleeve 4 is made slightly less in diameter across its outer circumference than the inner diameter of the overhanging flange 3. In order to insert the sleeve 4 into the Specification of Letters Patent.

Serial No. 158,631.

recess 2 in the end of the key, the upper end of the sleeve is provided with a plurality of longitudinal slots 7 which permit of the upper end of the sleeve being compressed as the same is forced past the overhanging flange As soon as the top of the sleeve at has been forced below the lower edge of the overhanging flange 3 the top of the sleeve springs outward securely locking said sleeve and with it the end of the chain or wire rope 5 into position in the end of the key.

By referring to the drawings it will be seen that the recess 2 is made of sufficient depth so that the lower end of the sleeve 4: will be spaced awa from the bottom of said recess to leave su cient space for the easy turning of the cross bar 6 secured to the end of the chain so that the same will not become twisted by the turning of the key.

It will also be seen by referring to the drawings, that above the lower edge of the flange 3 the recess 2 is preferably made to flare outwardly to facilitate the insertion of the sleeve l.

From the above description it will be seen that means are provided for securely looking a key to the end of a chain so that it is impossible to detach the same without leav ing visible evidence of the fact that the chain has been broken or the key tampered with. It will also be seen that the means provided for securing the key permit of the key being turned without turning the chain or rope to which it is attached.

The locking means above described are cheap to manufacture and easily assembled making a neat and finished appearance as there are no protruding parts.

While the invention has been described with particular reference to the details of construction the same is not to be considered as limited thereto, as many changes can be made and still fall within the scope of the invention set forth in the following claims.

What I claim is 1. A key for a watchmans clock comprising in combination a chain, a compressible locking sleeve, means for loosely securing one end of said chain to said sleeve, said key being provided with a recess having an overhanging flange, said sleeve being arranged to be forced past said flange into said recess for irremovably locking said sleeve and the end of said chain to said key.

for loosely securing the end of said chain to said sleeve, said sleeve being arranged to be forced past said flange to irreinovably locksaid sleeveand the end of said chain to said key.

3. A key for a Watchmans clock comprising in combination a chain, said key being provided W1th a recess having near its up per end a contlnuous overhanging integral flange, the portion of said recess above said Copies of this patent may be obtained for flange flaring outwardly, a compressible locking sleeve, means for loosely securing the end of said chain to said sleeve, said sleeve being arranged to be forced into the flaring end of said recess past said flange to 'irreznovably lock said sleeve and the end of said chain to said key.

In testimony whereof I have signed. this specification 1n the presence of two subscribing Witnesses.
